Ron Guth:
The 1850 Quarter is easy to find in most circulated grades and only becomes difficult to locate in MS64 and better conditions. Philadelphia made good-quality Quarters in this year and most are well struck, though some may show weakness in the denticles or some of the stars. The best example is a single PCGS MS67 that sold in 2014 as part of the Eugene Gardner collection, which included some of the finest Seated Liberty coins ever assembled.

In 1991, Larry Briggs identified three different obverse and three different reverse dies that were used to strike 1850 Quarters. Obverse 1 shows the base of a 1 in the outer rim just below and to the left of the first 1 of the date.
